Alfa Laval SRU rotary lobe pumps are engineered to provide reliable performance, trouble-free operation and superior energy efficiency for demanding applications in the dairy, food, beverage, personal care and pharmaceutical industries.

It is an excellent choice for duties that require contamination-free pumps to meet high standards of hygiene, low-shear and low-pulsation operation.

This pump handles both Cleaning-in-Place and Sterilisation-in-place, and can be supplied with thorough documentation to support rigorous validation requirements.

Alfa Laval SRU rotary lobe pumps are designed with features that maximise performance and minimize the risk of contamination.

These include a defined compression front cover sealing, rotor nut retention design, drainable pump head and ultra-clean surface finishes.

Understanding of flow patterns is vital to ensure high efficiency fluid transfer with low pulsation, low shear and low noise characteristics. Alfa Laval employs Computational Fluid Dynamics (CFD) to establish exact geometry for the rotors and rotor case.

To deliver reliable operation and low maintenance the SRU features a robust gearbox construction with heavy-duty shafts, torque locking assemblies and taper roller bearings throughout.

Alfa Laval SRU rotary lobe pumps comply with EHEDG, 3-A, 3.1 and FDA hygienic standards and have ATEX approval for use in explosive environments.
